Optical spectroscopy encompasses a wide variety of techniques used to study how matter interacts with light. Optical spectroscopy techniques are used in physics, astronomy, chemistry, biology, and ...

Near-infrared spectroscopy articles from across Nature Portfolio Near-infrared spectroscopy is a form of non-invasive imaging that applies near-infrared radiation (wavelengths 780 nm to 3,000 nm ...

Interview: “Security Should Be Built Into Embedded Systems From the Start, Not Added Later” — Andrew Doukhvalov, Head Of ...

The voltage (V)- and light power (P)-dependencies of electrochemical impedance spectroscopy (EIS) curves of perovskite solar cells (PSCs) are investigated over the entire (V, P) space rather than ...

We fabricated an antireflective structure on a polystyrene (PS) at terahertz (THz) frequency by using a hot-emboss method. Polystyrene was spin-coated onto a silicon substrate and then deformed by ...
